To all whomit may concern: Be it known that I, MIKE KOSZKOWSKI, acitizen ofoRussia, residing atNew -Kensington, county of Westmoreland,and State of Pennsylvania, have invented certain new and usefulImprovements in Wire-Cutters, of which the following is a specification.

. Thlsimventionrelates to improvements in machines adapted for usein.war, and partlcularly to types for cutting or severing wireentanglements.

The principal objectof the invention is to provlde an armored car withaplurality of cutting shears arranged at the front end thereof, theshears being operated by a mechanism within the car.

These and other like objects are attained .by the novelconstruction andcombination of parts hereinafter described and shown in the accompanyingdrawing, forming a materlal part of this disclosure, and -in whichFigure 1 is a front elevat ional View, showmg a portable wire cuttermade in accordance withthe invention, parts being broken away in orderto disclose the interior.

. Fig. 2 is a top plan view of the same, a

portion of the-cover being removed, and

Flg. 3 1s an enlarged fragmental vertical sectional view, showing thecutter operating mechanism.

In carrying out the invention use is made of an armored car 10, mountedupon wheels 11, and adapted to be propelled by any source of energy,preferably contained with- 1n the car.

Arranged upon the top of the car may be one or more turrets 12,containing rapid fir ng guns 13, the upper end surfaces of the car beingpreferably beveled as indicated.

Attached to the front of the car are a pair of brackets 15, from whichextend horizontal fixed shear blades 16, havingN shaped openings 17 atthe front, at the converging centers of which are recesses 18, theobject being to gather in the strands of wire against which the machinemay be directed.

Secured upon pivots 20 are blades: 21, having upper beveled surfaces 22,the blades Specification of Letters Patent.

the link bars 27, one end of the springs abutting against fixed collars33, secured upon the bars, while the lower end of the -springs rest uponthe extending brackets ,28, the springs being adapted to raise thelevers 24, so as to normally leave the openings 18 clear to receivewires or the like which may enter therein.

A motor 35 is secured within the car upon the floor, there being mountedupon the shaft of the motor a driving pulley 36, communicating powerthrough an open belt 37 to another pulley 38,:,mounted on a transverseshaft 40, carried in brackets' ll, secured upon the floor of the car.Also secured upon the shaft 40 are hubs 44, formed with arms 45 the sameextending outward in such manner that as the shaft is rotated, they makecontact with the bar 30, forcing it downward, opposing the springs 32,and causing the shear blades 21 to pass the openings 18 in the fixedcutter blades severing in an obvious manner any article which may beentered therein.

. It is to be understood that the shaft 40 ,is rotated at a high rate ofspeed, therefore the cutter blades are caused to move reciprocativelyacross the opening 18 in a r. 1d manner so that as the car 1s advanced tey cut' a passage for the same. Having thus described my invention whatI claim as new and desire to secure by Letters Patent, is

In a wire cutter for armored motor cars or the like, the combination ofa bracket havin a V-shaped slot secured tothe car with s ear bladespivotally secured to said bracket, lever shanks for said bladesextending into the car, link bars vertically disposed in said car towhich said lever shanks are pivotally secured, guiding brackets on theinner wall of the car through which said link bars are passed, springsencircling the upper portions of said link bars, fixed c01- lars on saidbars against which the, springs abut with vtheir upper ends, the lowerends 5 of said springs resting upon said brackets, a horizontal bar atthelowen ends of said link bars, a motor driven pulley, a shaft forsaicl -pul'ley, and operating fingers on said shaft adapted to engagesaid horizontal bar for operatin said shear blades. 10 In testimonywhered I have :aflixed my signature.
